3 Safety Instructions Please read these operating instructions carefully prior to using the product. The unit may be serviced only by qualified personnel. Be sure to withdraw the mains plug before opening the housing! Never replace the controller cards unless the unit has been disconnected from the power supply. Do only use the same type of fuses, 16 amps FF(See Repair Load Fuses ). Prior to inserting the mold cables, be sure to verify that all connectors have been properly connected (see Connections ). Check power supply cable and mold cables for potential defects on a regular basis! If the cable sheath is found to be defective, be sure to use a new connecting cable! Warranty The manufacturer grants a 2-year warranty for all slide-in controllers, with the period of warranty beginning on the day when the product is dispatched to the buyer. However, the warranty shall not cover damage caused by incorrect handling, wrong connection or improper use (see below). Return goods must be sent to HUMMEL AG, Geschäftsbereich EL Denzlingen, in their original packaging, postage prepaid. Intended Use units are industrial temperature controllers for controlling the melting temperature of hot-runner molds. To this end, the controllers determine the temperature of the respective control zone via a Thermocouple. This input is then used to regulate the power output for the heating element. To prevent overheating damage in case of malfunction, an external temperature fuse must be integrated into the heating circuits. The manufacturer shall not be liable for damage caused by improper use of the device. General Information A separate control zone is required for each load (zone) to be connected. A control zone consists of a temperature sensor input and a load output including a fuse. When connecting the mold cables, be sure to assign the cables to the correct connectors (see Connections ). Unused controller modules must be switched off. A heat-resistant flexible cable must be used as a connecting lead for the load circuits. For the Thermocouple, a special compensating lead is required! Cables are available as original accessories. 3

4 Set-Up Cleaning Service Disposal The device includes built-in, powerful fans that reliably prevent overheating of the output stage during operation. The corresponding ventilation slots are located on the underside and the rear side of the device. Make sure that air supply through these openings is not obstructed! The external surfaces of the device and the operating panel may be cleaned with a soft cloth saturated with alcohol. Please do not use acid cleaners or scouring agents. To prevent malfunction, the operating panel should only be cleaned after the device has been switched off. The device must be regularly subjected to a safety check complying with BGV A2 requirements (protection against accidents). It is recommended to clean the dust filters at regular intervals. Depending on the operating period and working condition, the filters should be replaced in the cassette. In addition, the ventilation slots should be checked for obstruction and cleaned if necessary. However, this task must be carried out by qualified service personnel and not by the user. No other maintenance work is required for the device beyond the tasks specified above. Should malfunction occur, please contact the manufacturer. Once the device has reached the end of its service life, please feel free to return it to the manufacturer for proper disposal. This device satisfies the essential protection requirements specified in pertinent EU Directives (as of 2005) 4

The unit features a CEE plug for this purpose. The main switch, which completely disconnects the device from the power supply (mains), is located on the rear panel. After performing a careful cable check, connect the mold to the controller. Connect the operating panel. If you use a PC for controller operation, connect the connecting cable to the interface connector. The alarm connector (accessory) allows you to establish a connection to the injection molding machine as well. Connect the power cable, switch on the controller with the main switch. Set the setpoint values. Be sure to switch off all control zones that are not used currently. If you use a touchscreen operating panel or a PC, you additionally need to start the control operation with HEATING ON/OFF. The controller will now heat up the mold in a uniform manner, thereby drying up any moist heating elements. As soon as the setpoints has been reached, the production process can be started on the basis of the factory settings (see also Soft-Start Ramp ). Should malfunction occur during the start-up process, the cause of the trouble is indicated by corresponding error messages. It is possible to exchange the operating panel in process. This causes no interruptions. Just connect your operating panel to the Operating panel connector. 9
